There’s nothing #basic about sustainable basics that reduce our impact on the world. Between organic fabrics and ethical manufacturing, everyday essentials can be much more than your go-to comfy clothes.
Finding good quality basics can be difficult with all the fast fashion brands running a muck, which is why we compiled a list of our favorites for you.
We focused on brands who use better, more sustainable, non-toxic materials, ethical sourcing and production, green business initiatives and more.
However, our new Brand Rating System is now live, which assesses brands against multiple additional sustainability-related criteria, including climate impact and product durability. For more information on this system, check out our explainer and look out for rated brands on the list below.
We independently research all featured brands and we ask them to confirm their claims. In many cases we personally review recommended products. This post contains affiliate links which means we may earn a commission if you buy something. Learn more here.

The exact style isn’t available anymore, but the Luxe Knit Cropped Cardigan is pretty close and has a cute button front.”
